well not sure if any of the ones I have are helpful or not. I have the source code for QOTO up, which is a fork of mastodon with a few code changes you may or may not want.
I also have a few docker containers that are useful. One is for testing custom mastodon code (spins up a container that compiles it for you and then hosts the services so you can go to the instance on localhost and test).
The other docker container is designed to be able to run mastodon bots ona . cron job with very little memory footprint.
